Find the degree of the monomial. 4g

gladu [14]

Answer:

The degree is 1

Step-by-step explanation:

Step 1: Find the degree

4g has a degree of 1 because the g is to the power of 1.

Answer: The degree is 1

Example: $4x^3$

Since the x is to the 3rd power, that means that the degree is 3

The circle given by : x^2 + y^2 - 6y - 12 = 0 can be written as:

deff fn [24]

Step-by-step explanation:

Given equation of circle is,

${x}^{2} + {y}^{2} - 6y - 12 = 0 \\ by \: compairing \: it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\2 g = 0 \: or \: g = 0 \\ 2f= - 6 \\ or \: f= - 3 \\ c = - 12$

again the another form of circle is,

${x}^{2} + {(y - k)}^{2} = 21 \\ or \: {x}^{2} + {y}^{2} - 2ky + {k}^{2} - 21 = 0 \\ by \: compairing \:it \: with \: \\ {x}^{2} + {y}^{2} + 2gx + 2fy = 0 \: we \: get \\ g = 0 \\f = - k \\ c = {k}^{2} - 21$

now equating the values of f in both equations,

-k=-3

i.e. k=3

therefore k=3

Now evaluate f(x)=2x^4-4x^3-11x^2+3x-6 for x=-2. F(-2)=

neonofarm [45]

Answer:

Step-by-step explanation:

f(x)=2x^4-4x^3-11x^2+3x-6

f(-2)=2(-2)^4-4(-2)^3-11(-2)^2+3(-2)-6

f(-2)=2(16)-4(-8)-11(4)-6-6

f(-2)=32+32-44-12

f(-2)=64-44-12

f(-2)=20-12

f(-2)=8

. Roger uses his truck to plow parking lots when it snows. He wants to find a model to predict the number of service calls he ca

expeople1 [14]

Answer:

4.1 calls

Step-by-step explanation:

The number of calls (c) that Roger expects to get as a function of how many inches of snow fall (s), is described by the following linear model:

$c(s)=0.8s+0.29$

Therefore, when s = 4.7 inches, the number of service calls that Roger expects is:

$c(4.7)=0.8*4.7+0.29\\c(4.7)=4.05\ calls$

Rounding to the nearest tenth, Roger will get about 4.1 calls.
